HAIR: Up To $1,000

Like blood, hair is asy enough to donate to a good cause (like Locks of Love).

But if you're at the end of your rope and your stellar mane is the best thing you've got going for you, it's entirely possible to sell it at a pretty sweet price point.

The trick is to keep it long and "virginal" as possible. That means no harmful hair dyes or other chemical treatments that could damage the quality. Buyers are likely looking to make wigs and they're not interested in your split ends, that's for sure.

YOUR PLACENTA: $8 (In China, anyway)

They can be eaten in a variety of dishes or ground into supplements that aid in everything from depression to breastmilk production and lactation.

New moms (including "Mad Men" star January Jones) typically use their own placentas and have them encapsulated, but the placenta trade is apparently booming in parts of Asia.

"Human placentas, banned by law from trade, are now selling like hotcakes on (China's) popular e-commerce platform where many customers purchase, cook and eat them as medicines believed to cure infertility, despite the danger of catching diseases," the Shanghai Daily News reported.

You can find them there at a steal – about $8 USD.

YOUR WHOLE BODY: Up To $1,000 Per Person

Hospitals and researchers rarely advertise clinical trials, so nailing down a pay range is tricky. Consumerist Commentary estimates one trial could earn up to $1,000 per person but it's important to think things through beforehand.

"There are no health benefits to participating in healthy volunteer medical trials and consequently the reason for your payment for time and inconveniences incurred. There is always the knowledge and greater purpose that in some way you have aided towards reducing the suffering of less fortunate people . The risks involved with Phase 1 Medical Trials can be likened to crossing the street. You could get hit by a bus although its unlikely , but there are things you can do to prepare yourself for medical trials to further insure your ultimate safety."

EGGS: Up To $8,000

When it comes to selling your powers of reproduction, women definitely have a leg up.

Eggs can be sold for as much as eight times the going rate for sperm, up to $8,000 for each completed cycle.

But that's likely because the process for egg donation is far more invasive than what men go through. The procedure.

"The egg donation cycle itself usually takes about 3-4 weeks, and involves self-injections with hormonal medications to help your ovaries produce multiple eggs. During this phase, you will have frequent office visits to monitor your progress," according to New York's Center for Human Reproduction.

KIDNEYS: Up To $10,000 A Pop

In a research paper published last week in Medical Anthropology Quarterly, Michigan State anthropologist Monir Moniruzzaman blew the lid off a massive illegal organ trafficking network in Bangladesh.

Kidneys can be sold for as much as $10,000 a pop and it's estimated that "organ trafficking accounts for roughly five to 10 percent of all the kidney transplants performed in the world," according to The Atlantic.

"Surrogates challenge our most basic ideas about motherhood, and call into question what we've always thought of as an unbreakable bond between mother and child. It's no wonder many conservative Christians decry the practice as tampering with the miracle of life, while far-left feminists liken gestational carriers to prostitutes who degrade themselves by renting out their bodies."
